Worldsteel published two potentially useful items recently. First, they published World Steel in Figures 2010 – which actually just covers up to 2009.
They also published their list of the largest steel producers in 2009. They publish the list in html and pdf formats. Here’s the link to the announcement. Unfortunately, the PDF file at the bottom of that page points to a file containing the 2005/6 data. So, if you want a PDF file of the 2009 data, click on ‘File’ in the Nerds spreadsheet below and select ‘Export as’ – PDF file is an option there.
